Two values

I found two duplicate IDs. What should I do? --Epìdosis 20:15, 9 November 2016 (UTC)

Obsolete

A few days (weeks?) ago all permanent links shifted from these IDs (format a\d+) to new CANTIC IDs, stored in CANTIC ID (P9984); I have added to P9984 the third party formatter URL https://crai.ub.edu/sites/default/files/autoritats/permanent/$1 and I have marked this ID as obsolete. --Epìdosis 18:17, 19 December 2021 (UTC)

@Epìdosis, thanks for the pattern change. Do you know how to find which WM projects are using this property in order to ping to them to change their WD invoke when the ID values were changed?. Thanks, Amadalvarez (talk) 05:48, 23 March 2022 (UTC)

It's not so easy; in Category:Pages using Wikidata property P1580 (Q61034951) I see only two tracking categories, both empty; here no {{{ExternalUse}} is present. These are the common methods to report these usages, I don't know others. I deduce that probably this property has always been used in very few to no Wikipedias. --Epìdosis 07:27, 23 March 2022 (UTC)

New property

Because of change of criteria about Id format, the University of Barcelona authority ID (P11686) has been created to replace this one. Thanks, Amadalvarez (talk) 19:17, 22 March 2023 (UTC)

CC:@ Epìdosis: Amadalvarez (talk) 19:41, 22 March 2023 (UTC)

@Amadalvarez: thanks for reporting me! I didn't propose a new property because I thought the catalogue now used just a subset of CANTIC ID (P9984), but I understand that the new one has been created because we are sure that some IDs in it aren't present in CANTIC, right? --Epìdosis 20:03, 22 March 2023 (UTC)

Yes. The code are the same but not all items are in both catalogue. Now I'm preparing the upload. Amadalvarez (talk) 21:10, 22 March 2023 (UTC)
